A goal of the Radio Camera Initiative is to develop a pipeline for streaming data in real-time on highly optimized platforms (e.g. GPUs, TPUs) that can be integrated into the digital backends being developed by the entire community. This effort is occurring against the backdrop of an explosive growth period in the software and algorithms used for radio astronomy motivated by the SKA, VLA/ngVLA, ALMA, MeerKAT, ASKAP, LOFAR, MWA, HERA, LWA, GMRT, EVN and VLBA etc. In the initial exploratory phase of the RCI, we have invited luminaries worldwide to present the cutting edge techniques being used for flagging, calibration, imaging and data processing in radio astronomy and beyond.
